Respawn Entertainment and EA confirmed that Star Wars: Jedi Fallen Order will have a sort of fast travel but not in the conventional sense. Players will still have to reach their ship in order to enable it.
According to Electronic Arts, Star Wars Jedi Fallen Order will have players moving through various maps on foot, with no ability to skip the trip to their ship or other landmarks.
The they sent to IGN stated that the developers "want players to explore and traverse (and re-traverse) the different planets", reinforcing Respawn's previous statements where they addressed players' concerns about the maps feeling slightly on rails and not like an open world.
Considering that Dragon Age: Origins utilised a similar system back in the day, it is not hard to imagine Respawn could pull their own version of BioWare magic that actually refers to creating wonderful RPGs and not the unnecessary crunch at the last moment.
Furthermore, EA's statement mentioned that explorable areas will be interconnected through discoverable shortcuts that will lead players to key areas so the traversal doesn't feel too repetitive despite walking over the same maps time and again.
On the topic of fast travel that is in the game, it is only the travel between planets. The player can walk to their ship, Mantis, and traverse between planets. EA did not elaborate on whether the players will get to visit planets as they see fit or if the story will take them through various worlds in linear fashion.
